Answer:
Sonar (sound navigation ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels
Working of SONAR:
It consists of a transmitter and a detector and is installed in a ship or a boat. The transmitter in SONAR produces and transmits powerful ultrasonic waves. ... The detector then converts the waves into electrical signals which are properly interpreted.
